To all whom it may, concern:

Be it known that I, JOHN E. FOX, a citizen of the United States, residing at Courtenay, in the county otStutsmz-rn, State of North Dakota, have invented certain new and use- 'ful lniprovements in Metallic Doors and I do hereby declare the following tobe lull, clear, and exact description of the invention, such as Wlll enable others skilled in the art to which it appertains to make and use theto provide a novel hinge joint between the door sections.

The inveiition aims as a further object to provide a track of novel construction including a curved section so proportioned with relation to the'other sections that, the binding which usually occurs in doors of this type is eliminated.

The detailed construction will appear in the course of the following description, in which reference 1s had to the accompanying drawings forming a art of this spec1i1cation, like characterso reference designating similar parts wherein Figure. 1 is a throughout the several views,

ance'with the present invention. Fig. 2 is a vertical transverse section of such structure which as arbitrarily shown, isa freight car, thedoor being removed. Fig. is a similar view showing vthe door With its sections assembled for use. Fig. .4 is an enlarged vertical transverse section illustrating the connections between two adjacent sections. f Fig. 5 is a detailed perspective .vieW of the lowermost of the above mentioned door seetions; Fig. 6 is a horizontal section of a vertical track or guide. Fig. 7 is a vertical section of a horizontal track or guide, which is cor structed to acconunodate two doors, one at each side of the car. Fig. 8 is a plan View showing a curved track section interposed between the vertical and horizontal sections end elevation of a clamp forming an element of lungs joint between the sections.

Referring to the accompanying drawings,

the numeral 1 indicates the structure in.

connectiop'with which the door embodied in the present invention is used. Such structure as arbitrarily shown, is a car, although itwill be understood that the door may be longitudinally along their upper and lowers.

edges i'nto annular ci)nforination,' as. at-6, so as to afford ahollow promoting head, the ex;

.treniities ofsuch beads terminating short of or in spaced relation to the. material ofjhe section adjacent thereto. It will thus be seen that an open recess 7 of arcuate oiitlinesf occurs between the upper and lower ends of the sections and the edges of the heads 6 adjacent thereto. The lower edge of the section 3 and the upper ed e of the section 4- are similarlyconstructei tions thus constructed are united in hinged relation by clamps 8, preferablycoextensive The clamps 8 'illustrated in Fig; 9, conform in shape to the ad jacen t beads which abut cine another and are accordingly formed with interrupted loops 9, of annular outline between which an in .wardly projecting rib 10 occurs, thef b 10 loops being adapted toenter the spaces 7 in such inovcinent. The lower section 4 V has its bottom portion cut away a distance from the sides and bent forwardly'ata right angle to engage the fioor,'as clearly shown at 11, in Fig. 5. The upper edge of the section 3 is unbeaded. p l

The door thus constructed is guided in its movement by tracks arranged at each side of illustrated in Figs. 3 and 7. and hi 9 is an the door frame. Such tracks are designated The door 'secdbl-partition 19,

, "do pend from the ceilinggenerally by the niuneral 12, and comprise a vertical section 13, a curved section 14, and

a horizontal section 15. The sections 13 and I lg-are of U or channel-shape in cross'sec- 6- t ijonand together with the section 15 are tolthe frame of the car by fastening bolts-16. The section '15 embodies upper and lower channels 17 and 18, defined by the v.side walls ,ofsaid section and a lon itu'dinal arallel to said side wa ls. The partition- 19 efines the width of the section lfifand'theside walls terminate at opposite ends; short of the ends of. said partition,

ereby afi'ording upper and lower projecting {ipitions 20 and '21, which are continnations I the respective channels 17'and 18. 'Said e'c'tin'g portions are formed at their ends 1i g per tenons 22 and the sections 13 are forine at their upper endswith tenons'23. Each section 14 is likewise provided at its ends with tenons 24,- designed to bear against the tenons 22 and 23', an to' aiford'a seat for said section in its imposed relation. It is to be noted that the channel of the section 14 radually increases in width from its ends .to its central portion, in order to prevent the door sections from becoming frictionally jammed therein.

It is to be noted that the door on one side of the car will move into the channel 1.7 when said door is raised, and that the door .(m the other side of the car will in like'manner move into the channel 18. This arrangement permits of both doors being sustained in raised position at the same time, the one door overlying the other as will be readily understood. For; the purpose ,of holding said doors in their raised position, hooks are provided which pivotally deadjacent the door the several parts without the same in juxtaposed tions 5 of each door is provided onits outer snri'ace with handles 26, by means of which the doors may be raised or lowered.

If desired, suitable catches'27 may be provided on the door frames for engagement with the extensions 11 to prevent the same fromwholly closin the door opening, as in the operation of u oading coal.

From the foregoing description, it will be seen that simple and efficient means are provided for accomplishing the objects of the inventibn, but While the elements herein shown and described are welladapted to serve the purposes set forth, that yarious minor changes may be made in theproportions, shape and arrangement of departing from the spirit and scope of the.invention,' as defined in the appended-claims.

What is claimed is:

A door of the typeset forth comprising sections provided along opposite parallel edges wit bent portions forming rojecting ho low annular heads, the edges 0 said bent portions being spaced away from the mate rial adjacent thereto, pr slng a pair of lnterru conforming to said bea and clamps, each comted annular-loops. sand surrounding airs.
